[syslog-ng]syslog-ng web-based monitoring tool

I'm currently logging a bunch of machines remotely over stunnel via syslog-ng. All loggin on the loghost goes to a mysql database. Does anybody know of a web-app to parse the entries from the database in a nice format? Re-coding is not a problem. Anything that comes close to this would be beneficial, as long as it's open sourced. Thanks in advance, ~Matt
